General

Optiva™ L-band fiber optic intra-facility links are a high-performance, cost-effective alternative to coaxial cable. They provide much longer transmission distances than copper cables, which simplify network design, ease installation and even enhance immunity from EMI, RFI and lightning. These transmitters and receivers take the best RF design features of Emcore’s extensive families of products and combine them into a compact package compatible with the Optiva™ OT-CC-16 chassis. The Optiva™ family’s wide range of RF, video, audio and data transport products include a unique data bus design that provides a higher level of monitoring and control with a single chassis mix and match flexibility. The final result is a chassis system that can be factory or user custom configured to meet a wide range of fiber transport applications. All units come as an insert card version. The cards can be inserted into the Optiva 3RU 16-slot, 19” rack-mountable card cage (OT-CC-16), 1RU 4-slot 19” rack (OT-CC-4-1U) or one of the smaller Optiva™ Desktop Card Racks (OT-DTCR Series). The power supply must be the 12 volt version.

Installation Module Installation

Align the top and bottom card edges in the chassis channel and slide firmly into the back plane.

Tighten the top and bottom module screws to secure in chassis. Transmitter Installation

Prior to connecting the input RF connector, ensure that the LNB power switch is in the desired mode and verify with the LNB LED. Refer to figure 1.

Connect satellite signal to the RF input connector. Press and release the PEAK button to optimize the RF level to the laser. (Optional.) Insert the SC/APC connector in the fiber output connector socket. (See “Optics Handling”

section.) Receiver Installation

Insert the SC/APC connector in the fiber input connector socket. Connect satellite signal output to the RF output connector. Press and release the H/L button to adjust the output RF to the desired level. Reference the LED bar graph to ensure optimized operation. Signal level can be monitored through the provided SMA monitor port.

Operation

Peak Signal Optimizer Gain Control Mode (PEAK)(TX) The peak button is designed to optimize the RF signal level introduced to the laser. This ensures that the transmitter module is providing the optimum performance. Pressing the “PEAK” button once causes the circuits to adjust the RF gain up/down automatically to the ideal RF power based on the RF level at that moment. In SGC mode the module will hold this level stable within a window. In MGC mode this feature is only instantaneous and will not adjust for level variances.

Smart Gain Control Mode (SGC)(TX) Every step has been taken to ensure simple hands free operation. The Smart Gain Control mode provides for a wide input range optimized to the laser input. Variances to the input RF level are automatically adjusted, but in a unique way to minimize cross-talk between different transponder signals (patent pending). This will provide the lowest possible noise and distortion. The transmitter RF LED indicator will display the input RF status:

Red: The Input RF is far above the optimum SGC range. Blinking Green: The Input RF is above the optimum SGC range. Green: The Input RF is within the optimum SGC range. Amber: The Input RF is below the optimum SGC range. Blank: The Input RF is below the detectable range.

Manual Gain Control Mode (MGC)(TX) The Optiva L-band transmission system is designed to work in a wide frequency spectrum. In the event of the presence of undesired out-of-band signals that vary greatly in level, or for situations such as up-links where a very stable gain is introduced, Emcore recommends that the transmitter be placed in MGC. To use MGC mode, on the transmitter press and release the MGC ON/OFF button. The MGC LED indicator will illuminate in MGC mode. Use the H/L buttons to bring the RF level into range. The transmitter RF LED indicator will display green when the input RF is within the optimum range. Alternatively, pressing the “PEAK” button once will adjust the Tx RF gain for the ideal RF laser power on the laser, based on the RF power into the Tx at that moment. In manual gain control, the gain setting remains constant regardless of the RF input power changes.

Remote Monitoring

Simple Network Management Protocol (SNMP) The Optiva System is designed to provide remote status and control monitoring via SNMP monitoring programs. Use of this feature requires the use of a network management system agent card (NMS) that serves as the interface between the data retrieved from the system cards and the management program. Management Interface Bases (MIB’s) are available with the purchase of the NMS card (OPV-CTLR-IC). The MIB defines the detailed variables and protocol for the particular product.

Optics Handling & Safety Working with fiber optic cables and interfaces require a clean dust free environment. The optical power is confined in the optical core only a few microns in diameter. Small particles of dust can block the proper transfer of light through the connectors. It is therefore important to keep connectors as clean as possible, and when in doubt of the cleanliness of a connector, clean it prior to inserting into a transmitter or receiver receptacle. A number of events can damage fiber optic connectors. Unprotected connector ends can experience damage by impact, airborne dust particles, or excess humidity or moisture. Never touch the fiber end face of the connector. When cleaning fiber optic connectors use only Industrial grade 99% pure isopropyl alcohol, lens-grade, lint-free tissue, and optionally canned dry air. Alternatively, there are a number of simple, effective products that are specifically designed for cleaning fiber optic connectors. Never look into an illuminated fiber end. Disclaimer Every attempt has been made to make this material complete, accurate and up-to-date. Users are cautioned that EMCORE reserves the right to make changes without notice and shall not be held responsible for any damages, including consequential, caused by reliance on the material presented, including, but not limited to, typographical, arithmetical, or listing errors. WARNINGS, CAUTIONS, LIABILITY, WARRANTY AND GENERAL NOTES

Safety Considerations When installing or using this product, observe all safety precautions during handling and operation. Failure to comply with the following general safety precautions and with specific precautions described elsewhere in this manual violates the safety standards of the design, manufacture, and intended use of this product. Emcore assumes no liability for the customer's failure to comply with these precautions.

The fiberoptic laser transmitter used in Emcore’s Optiva link contains a class IIIb laser product as defined by the U.S. Department of Health and Human Services, Public Health Service, Food and Drug Administration. This laser product complies with 21 CFR, Chapter I, Subchapter J of the DHEW standards under the Radiation Control for Health and Safety Act of 1968. The laser operates at nominally 1310 nm with less than 30 mW optical output. The typical optical output for this product is less than 10 mW. The protective laser plug-in module housing prevents a user from being exposed to hazardous optical output levels. Since there is no human access to the laser output during system operation, no special operator precautions are necessary when fiber is connected to the transmitter and receiver. During installation, service, or maintenance, the service technician is warned to not look directly into the end of the fiber connector or the fiber. The light emitted from the fiberoptic connector or any fiber connected to the transmitter is invisible and may be harmful to the human eye. Use either an infared fluorescent screen or an optical power meter for optical output verification. All handling precautions as outlined by Federal agencies or other authorities of class IIIb lasers must be observed. Do not attempt to modify or to service the laser diode module. Return it to Emcore for service and repair. Contact the Emcore Customer Service Department for a return authorization and further instructions.

Electrostatic Sensitivity

Observe electrostatic precautionary procedures. Semiconductor laser transmitters and receivers provide highly reliable performance when operated in conformity with their intended design. However, a semiconductor laser may be damaged by an electrostatic charge inadvertently imposed by careless handling. Static electricity can be conducted to the laser chip from the center pin of the RF input connector, and through the DC connector pins. When unpacking and otherwise handling the transmitter, follow ESD precautionary procedures including use of grounded wrist straps, grounded workbench surfaces, and grounded floor mats. Exposure to electrostatic charge is greatly reduced after the transmitter or receiver has been installed in an operational circuit. Service

Do not attempt to modify or service any part of the system other than in accordance with procedures outlined in this Operation Manual. If the system does not meet its warranted specifications, or if a problem is encountered that requires service, return the apparently faulty plug-in or assembly to Emcore for evaluation in accordance with Emcore's warranty policy. When returning a plug-in or assembly for service, include the following information: Owner, Model Number, Serial Number, Return Authorization Number (obtained in advance from Emcore's Customer Service Dept.), service required and/or description of the problem encountered.

Warranty Emcore warrants to the original purchaser all standard products sold by Emcore to be free of defects in material and workmanship for one (1) year from date of shipment from Emcore. During the warranty period, Emcore's obligation, at our option, is limited to repair or replacement of any product that Emcore proves to be defective. This warranty does not apply to any product that has been subject to alteration, abuse, improper installation or application, accident, electrical or environmental over-stress, negligence in use, storage, transportation, or handling.

This warranty is the only warranty made by Emcore and is in lieu of all other warranties, expressed or implied, except as to title, and can be amended only by a written instrument signed by an officer of Emcore.
